Clarifying the nomenclatural history of Tovomitopsis, a Brazilian endemic genus of Clusiaceae

Tovomitopsis Planch. & Triana is a Brazilian Atlantic Forest endemic genus composed of two species: T. paniculata (Spreng.) Planch. & Triana and T. saldanhae Engl. An investigation was conducted to clarify the nomenclatural history of Tovomitopsis . We report the results of this investigation, provide an updated description of the genus, and propose lectotypes for T. paniculata and its synonyms: Tovomita foliosa C.Presl and Tovomita paniculata Cambess. We also propose lectotypes for T. saldanhae and for the new synonym Clusia angustifolia Engl.
